Ukuqina kungenye yezinto ezisetshenziswa kakhulu zemishini yezinto zensimbi.Iucingo lwensimbiifektri yethula indlela yokuhlola esheshayo neyongayo yokuhlola ubulukhuni.Kodwa-ke, ngenxa yokuqina kwezinto zensimbi, ayikho incazelo ebumbene futhi ecacile ehlanganisa zonke izindlela zokuhlola ekhaya naphesheya.Ngokuvamile, ubulukhuni bensimbi buvame ukubhekwa njengokumelana kwezinto ezibonakalayo epulasitiki, imihuzuko, ukugqoka, noma ukusika.
Ikhoyili enkuluucingo lukathayelaekulungiseni ibanga lokucwiliswa kwe-zinc, gcina isivinini sangempela singashintshiwe, ngokusho kwe-t= KD ukucacisa isikhathi sokucwiliswa kwe-zinc (1), lapho: isikhathi sokucwiliswa kwe-zinc sihlala njalo, thatha i-4-7D ububanzi bocingo lwensimbi mm , bese ulinganisa ibanga lokucwiliswa kwe-zinc.Ngokulungisa ibanga le-zinc dip, isikhathi sokucwiliswa kwe-zinc sentambo yensimbi yezicaciso ezihlukahlukene singafushaniswa ngama-5s ngokwesilinganiso.Ngale ndlela, ukusetshenziswa kwe-zinc ngethani locingo lwensimbi kuyehla kusuka ku-61kg kuya ku-59.4kg.
I-Hot dip galvanizing isendaweni eshisayo ye-zinc liquid dip plating, isivinini sokukhiqiza, ukunamathela okuwugqinsi kodwa okungalingani, imakethe ivumela ukushuba kwama-microns angu-45, kufika kuma-microns angu-300 ngaphezulu.Imnyama ngombala, idla insimbi eningi ye-zinc, yenza ungqimba olungenayo olunesisekelo sensimbi, futhi inokumelana nokugqwala okuhle.I-hot dip galvanizing ingagcinwa amashumi eminyaka endaweni yangaphandle.Ukuvikelwa kwe-zinc enamathela ku-matrix yensimbi kunezimiso ezimbili: ngakolunye uhlangothi, nakuba i-zinc isebenza kakhulu futhi kulula ukuyikhipha kune-iron, kodwa ifilimu yayo ye-oxide ayikhululekile futhi ihlangene njenge-iron oxide.Ungqimba oluminyene lwe-oxide olwakhiwe phezulu luvimbela ukuqhubekela phambili kwe-oxidation ye-zinc ngaphakathi.
Ikakhulukazi emva passivation ofothayelaungqimba, ingaphezulu longqimba lwe-oxide likhulu futhi lihlangene, ngokwalo linokumelana okuphezulu kwe-oxidation.Ngakolunye uhlangothi, lapho ubuso bongqimba olunathayela bonakalisiwe, buveza i-matrix yensimbi yangaphakathi, ngoba i-zinc isebenza kakhulu kune-iron, i-zinc izoba nendima yokunikela nge-zinc anode, i-zinc izokwenziwa oxidized ngaphambi kwensimbi, ukuze ivikeleke. ungqimba lwensimbi ngeke lonakale.
